What Is Auto Smart Film?
Auto Smart Film is a self-adhesive PDLC (Polymer Dispersed Liquid Crystal) smart film designed specifically for automotive, railway, and marine glass applications. Applied directly to the interior surface of existing glass — including panoramic sunroofs, side windows, rear windows, subway windows, and cruise ship glass — it instantly switches between transparent and frosted states at the touch of a button.
When powered on, the film is crystal clear, allowing full visibility and natural light. When powered off, it turns into a frosted, opaque white surface that provides instant privacy, blocks glare, and reduces heat inside the vehicle cabin.
Unlike aftermarket window tint film that is permanently dark, Auto Smart Film gives you on-demand privacy and solar control — you choose when you want clear glass and when you want frosted.
Why Choose Auto Smart Film for Your Vehicle?
Dynamic Privacy
Switch your car sunroof from clear to frosted in less than a second. No more reaching for the sunshade or pulling down the roller blind. One touch on your control remote or smartphone app, and your panoramic roof becomes a private, shaded surface — perfect for passenger comfort, napping on long drives, or maintaining privacy in parked vehicles.
99% UV Block Protection
Auto Smart Film blocks ≥99% of harmful ultraviolet (UV) radiation. This protects your skin from sun damage and prevents interior upholstery, leather seats, and dashboard materials from fading, cracking, or deteriorating under prolonged sun exposure.
82% Infrared Heat Rejection
With ≥82% infrared (IR) blocking rate, Auto Smart Film dramatically reduces solar heat buildup inside your vehicle. This means cooler cabin temperatures in summer, less reliance on air conditioning, and improved fuel efficiency or electric vehicle range.
Ultra-Low Power Consumption
Operating at just ≤5W/m² with a safe 60V DC power supply, Auto Smart Film consumes minimal energy — negligible impact on your vehicle's electrical system compared to powered sunshades or motorized blinds.
Fast Response Time
The film switches from OFF to ON in ≤30 milliseconds and from ON to OFF in ≤200 milliseconds — near-instant transformation, no waiting.
Wide Operating Temperature Range
Engineered for automotive environments, Auto Smart Film operates reliably from -30°C to 95°C — handling everything from freezing winter mornings to scorching summer dashboards and sunroof surfaces exposed to direct sunlight.
Long Service Life
Designed to last 10-15 years with ≥100,000 switching cycles — built for the long-term demands of daily vehicle use.

Layer-by-Layer Construction
Auto Smart Film is engineered as a multi-layer laminate:
PE protective film — outermost layer, removed during installation
ITO conductive film — transparent conductive layer, applies the electric field
PDLC layer — the liquid crystal core that switches between clear and frosted
ITO conductive film — second transparent conductive layer
OCA (Optically Clear Adhesive) glue — bonds the film to the glass
PET substrate — structural backing layer
Silica gel — pressure-sensitive adhesive for direct glass application
The total film thickness is only 0.13mm — thin enough to apply to virtually any glass surface without visible edges or bulk.
Key Features
Touch Screen & Projection Capability
When in the frosted (OFF) state, the film surface functions as a projection screen. Project videos, images, or presentations onto the film from inside the vehicle — turning your sunroof or side window into an entertainment display. Imagine watching a movie under the stars through your panoramic roof.
Heat-Resistant & Anti-Scratch
The film is engineered to withstand the high temperatures generated by direct sunlight on automotive glass. The protective surface layer is also anti-scratch, resisting damage from cleaning, dust, and daily handling.
Anti-Noise
PDLC film dampens sound transmission through glass, reducing road noise, wind noise, and external traffic sounds inside the cabin — creating a quieter, more comfortable ride.
Multiple Control Methods
Auto Smart Film can be controlled via:
Remote control — handheld wireless remote
Wall switch / dashboard button — integrated into your vehicle controls
Smartphone app — iOS and Android control
Voice control — compatible with smart voice assistants
Touch control — tap the glass surface to switch
Environmental Protection
Free of harmful chemicals and RoHS compliant, Auto Smart Film is an eco-friendly upgrade that replaces disposable sunshades, opaque window covers, and single-use thermal films.
Security
When parked, switching the glass to frosted state hides your belongings from view — adding a layer of visual security without the need for curtains, shades, or opaque covers.
Applications Beyond Cars
Panoramic Sunroofs
The most popular application. Turn your panoramic glass roof from a full sun exposure surface into a private, shaded canopy at the touch of a button. Perfect for luxury sedans, SUVs, and electric vehicles with large glass roofs.
Side Windows & Rear Windows
Apply to side windows for on-demand privacy — ideal for executive vehicles, limousines, and luxury sedans where rear-seat passengers want privacy from the outside world.
Subway & Train Windows
Transit and railway applications benefit from switchable glass — passengers can adjust light and privacy throughout the journey. The film also reduces glare and UV exposure for commuters.
Cruise Ships & Marine Glass
Yacht windows, cabin glass, and ship portholes benefit from Auto Smart Film's UV and IR blocking, privacy control, and ability to withstand humid marine environments.
RVs & Campervans
Motorhome windows and skylights become instantly private and shaded — no more clunky blackout curtains or blinds.
Emergency Vehicles
Ambulances, police vehicles, and security vans can switch windows to frosted on demand to protect patient or passenger privacy.
Installation Guide
Auto Smart Film is a self-adhesive, apply-in-place film — no factory lamination required. It is applied directly to the interior surface of existing glass:
Prepare the glass — thoroughly clean the interior glass surface, removing all dust, grease, and residue.
Measure and cut — cut the film to the exact shape and size of your glass panel, allowing a small margin for trimming.
Peel the liner — remove the PET release film from the adhesive side.
Apply and smooth — carefully position the film on the glass and smooth it from the center outward, removing air bubbles.
Trim edges — trim excess film along the glass edges with a precision knife.
Connect wiring — connect the film's conductive busbars to the 60V power supply and control unit.
Professional installation is recommended for best results, especially for complex shapes like curved panoramic sunroofs.
Frequently Asked Questions
Q: Can Auto Smart Film be applied to any glass?A: Yes. It works on flat and slightly curved automotive glass, including sunroofs, side windows, rear windows, and windshields (where legally permitted). It is not recommended for deeply curved or compound-curved surfaces.
Q: How long does the film last?A: The expected service life is 10-15 years under normal automotive use, with a tested 100,000 switching cycles.
Q: Does it work in hot weather?A: Yes. The operating temperature range is -30°C to 95°C, specifically engineered to withstand the high temperatures inside parked vehicles in summer.
Q: Can I cut it to size myself?A: Yes. The film can be cut to custom sizes. We supply both sheet and roll formats — 1200mm and 1500mm widths available.
Q: Does it block all light when off?A: No. In the OFF state, it is frosted and opaque to visibility, but still transmits about 51% of light — creating a bright, diffused glow rather than a darkout surface.
Q: What power supply does it need?A: The film operates at 60V DC, powered by a control unit that converts your vehicle's 12V/24V supply. Power consumption is ≤5W/m² — negligible.
